Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.

The role

Advanced language skills and verifiable experience as being fluent in Spanish.
A willingness to take our skills verification test to assess your suitability for our Domain Expert participant pool
Strong attention to detail and the ability to concentrate on complex tasks for up to one hour at a time
A reliable and fast internet connection and access to a computer
A willingness to self-declare your earnings, as our participants are self-employed
A PayPal account to receive payment from our clients

What you’ll be doing in the role

Completing AI training tasks such as analyzing, editing, and writing in Spanish
Judging the performance of AI in performing Spanish prompts
Improving cutting-edge AI models
